The sound quality on this is great, especially at high volume and you will want to crank it. I don't know these are considered true classic hard rock tunes but to my ears they sound like it. If you like the sound of classic 70's sounding hard rock music (I know, it's an '81 release), you gotta hear this. Maybe you already have and I just missed the boat until a few years ago. I don't like what I have heard from them after this album so don't judge this by the others if that's all you have heard.
